Walter Filter or Water Purifier | What’s the Big Difference?

When it comes to clean, healthy drinking water, many of us are undecided whether we require a water filter or a water RO purifier. Both give an assurance of clean drinking water, but which is best for your household? There are a lot of options of water filter systems in the market and it can be quite daunting to interpret the industry jargon when it comes to the health of your family. Being able to clearly distinguish between the two will help you make a well-informed decision. 

Read on to understand what a water filter is, what a water purifier is and ultimately the difference between water filters and water purifiers.

What is a Water Filtration System?

A water filter system is designed to remove or reduce the number of contaminants in your water by using a physical barrier such as a sediment filter, a chemical process such as absorption through an activated carbon filter, or a biological process such as using Ultraviolet light. Regardless of the process in which your water filter uses, impurities such as bacteria, cysts, sediments, disinfection by-products like chlorine, other chemicals such as volatile organic compounds (VOCs), heavy metals and similar, can be eliminated from your water supply. The removal of these particles can instantly improve your water quality by making it taste and smell better.

Types of Water Filter Systems:

There are many types of household water filtration systems to choose from. We have compiled a quick list of a selection of the most common household water filtration systems:

  1. Activated carbon filters
    Activated carbon (AC) is used in water filtration as it is extremely porous and has large surface area to remove contaminants and impurities through the process of chemical adsorption. A water filter system that uses an activated carbon filter can do so with a stand-alone carbon filter or a carbon block insert. Typically, fine AC powder is pressed into blocks or a bed of loose granular AC is used.                             
  2. A sediment water filter
    A sediment water filter acts as a sieve, sieving outing large particles like sand, clay, silt, and other organic impurities that are present in your water. Of course, it is important to note that only particles exceeding the pore size of the sediment filter are removed.
  3. An Ultraviolet filtration system
    Within an Ultraviolet filtration system, Ultraviolet light is used to deactivate microbiological organisms present in water. However, it does not remove bad taste and odour.
  4. An Ultra-Filtration system
    An Ultra-Filtration system enables the passage of water through a semi-permeable ultra-filter membrane. By using this water filter, you will remove harmful bacteria and suspended particles from your water supply.

Some water filter systems go one step further to remove the healthy minerals that naturally occur within your water supply, too. This is where water purification comes in.

What is a Water Purification system?

A water purification system performs the same function as a water filter, plus it also demineralises the water. This means that you do not get the option to retain the naturally occurring minerals within your water, which you may wish. The naturally occurring minerals are removed completely as part of the purification process.

There are two types of water purification systems that you can choose from:

  1. Distillation
    Distillation is a process which involves the conversion of water into steam before turning it back into water. During these conversions, contaminants are separated from your water and the bacteria and viruses are destroyed. Unfortunately, along with these contaminants can often be the naturally occurring minerals due to the system being unable to distinguish between the two.
  2. Reverse Osmosis
    Reverse Osmosis (RO) is the most used water purification process. In an RO purifier, water is forced under pressure to pass through a semipermeable membrane which has extremely small pores. These pores in the membrane block contaminants but allow water molecules to pass through. Reverse Osmosis systems are highly effective for water purification. However, since it takes out all dissolved components in water, it cannot differentiate between the good and bad minerals. Again, this can result in removing the healthy, minerals from your water supply, too.

    Whether you purchase a water filter or a RO water purifier, you will receive a glass of clean drinking water. However, now that you know the difference between the two, here is one of the key debates in selecting the right system for you:
